Drew Peterson’s lawyer praised the arrival of FBI assistance in the search for Stacy Peterson, the ex-Chicago police sergeant’s missing fourth wife. "My hope is that this will move from the witch hunt that it has become and go back to a missing person case," Peterson’s lawyer told the Chicago Tribune.

The agents were briefed yesterday and have commenced what is being called a criminal missing person investigation. The bureau has the power to summon teams of Navy divers for assistance in searching bodies of water. Peterson has come under intense scrutiny in his wife’s disappearance, which has also spawned an investigation into the death of his third wife, which had previously been considered a suicide.
